Just wanted to see ur thought for everyone to read... you make a valid argument.The only person I know of that has proven that a SD-2 chip can be tune to run fast is Walt Judy which he runs TSM- He also builds his own engine and has a lot of secrets to the process- its not just the SD-2 chip that makes his car fast. To my knowledge as far as the THS class- no one has come close to running 9 second passes with any stock ECM/chip in the past three years. The fastest I ran with a stock ECM/Mass air chip was 10;21 @ 132 in THS full trim @3675 including my weight in 2015 @ BG. Plus its highly unlikely that a novelist tuner guy can tune and SD-2 chip to compete with any of Cal Hartline cars that running a Fast in the THS class. Plus anyone who is running an SD-2 chip will not have track side years of experience and support to tune the car as a Cal Hartline THS car would. That's my case my friend- rebuttal if you like.
